MICHAEL C. ARMOUR, OF CHICAGO, ILLINOIS.

OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 305,265, datedSeptember 16, 1884.

Application filed October 23, 1883.

To all whom it may concern:

Be it known that I, MICHAEL O. ARMOUR, of the city of Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements in Oil-Stoves, also Applicable to GasStoves, ofwhich the following is a specification.

My invention relates to that class of oil or gas stoves in which theheat, after acting directly upon the vessels placed upon the top plate,passes into or around an oven or ovens to a suitable escape-aperture,heating the oven or ovens in its passage. The said class of stovesusually embrace a bake-oven and a warming-chamber, the former of whichonly is heated by the passage into and through it of the heat andproducts of combustion, the warming-chambers being heated entirely byradiation. I

My present inventio11,which is an improvement upon the class of stovesreferred to, consists, first, in an improved mode of arranging andholding the removable lampsin the space under the top plate, whereby thelamps may be withdrawn from the position in which they are used forheating to a position beyond the front limit of the stove, where theymay still remain connected with their supports or be lifted therefrom,and thus entirely detached from the stove. I l I My invention alsoconsists in providing a space for an extended oil-pot, and in employingan oil-pot of greater cubical capacity than has been heretofore used inthis class of stoves, whereby less frequent attention to the supply ofoil is required.

My invention also consists in an improved construction ofwarming-chamber and its arrangement with respect to the stove-frame,whereby it may be cheaply and conveniently attached thereto, and removedtherefrom should said oven have become damaged by use, wear, orshipment.

My invention consists, further, in other details of construction andcombinations of parts, as hereinafter particularly specified.

In the accompanying drawings, Figure l is a perspective view of myimproved stove with the doors of the bake-oven and warming-cham- (Nomodel.)

Similar letters of reference indicate similar parts in the respectivefigures.

A A are the outer cast frames of the stove, of any suitable orornamental design. The lower edge of each frame is made L- shaped, as ata, to receive a board or boards, b, covering the entire base area of thestove.

B is the top plate of the stove, the front part of which is perforated,in the usual manner, to receive the ordinary movable section and covers,as shown. The rearpart of said plate, or that portion which occupies theovenspace, is open andrcceives a central section, a, constructed inopen-work, as shown in Figs. 1, 2, and 3, which section is removable.Below the top plate is a casting, d, bolted thereto, and which serves asa guide for the tops of the removable lampsC.

Near the lower edges of each of the side frames A, and extending fromthe front to the rear of the stove, is a longitudinal groove, 6,

'in each of which rests a longitudinally-moving way, a, which wayssupport one side of .the lower part of each of the lamps C. The

inner side of each lamp rests in a similar way, 0, supported on a ledgeor rabbet, 0', formed in the central casting, d, the foot of which issecured to the board I). The casting (1 extends upward between the twolamps C and unites with the central portion of the casting d. It is notnecessary that the upper part of the casting or partition (1 between thelamps should be used, but if used it is made preferably, in open-work,so as to allow a free circulation of air between the two .lamps,although, if desired, itmay be solid. The ways 0 and e which support thelower portions of the lamps,

are adapted to slide in or out with the lamps,

being united thereto in some suitable manner.

k 50 her open. Fig. 2.is a vertical longitudinal As the ways extend backwithin the grooves I00 stove.

e 6' under the oven-space, when the lamps are drawn out beyond the frontlimit of the stove, a sufficient length of ways is still within thegrooves to support the lamps and keep them from being entirely detachedfrom the The outward movement of the ways upon their supporting-ledgesand the inward movement of the lamps may be limited by suitable devices,or the ways may be made to draw out entirely away from the front of thestove. As shown in Fig. 1, (detached view,) a bar, 6", extends acrossthe front, connecting the ways 6' c, and is furnished with a handle, 0enabling the ways and lamps to be drawn out together. r

The lamps are of a construction shown in other patents issued to me, andneed not here be specially described. WV hen in position, the tops ofthe lamps are in a plane sufficientl y below the under side of the topplate to allow the heat and products of combustion to take the directionshown by the arrows in Fig. 2.

The Warming-chamber is shown by D. It is made of tin in the form of abox having all its sides closed except that opposite its door, which isrepresented by g and fastened to the frame A. The chamber is insertedwithin the frame A from the rear of the stove, and when so inserted issuitably bolted or attached to the frame. The chamber may, when desired,be removed by drawing it out after its bolts have been detached, asindicated by the arrows at the rear of Fig. 2. This-feature of myinventionviz., the detachability of the warming-chamber-I consider ofimportance. Heretofore in stoves of this class the connection betweenthe warming-chamber and other parts of the stove has been of a morepermanentcharacter, and as the warming-chamber, because of its exposedsituation, is more liable to damage and wear than other parts of thestove, it is important that it shall be so arranged that it may bereadily detached and another substi tuted when necessary. Heretofore instoves of this class the same sheet of tin has served for one side ofboth the war]hing-chamber and bakeoven and another sheet for the backsthereof; but in my present invention the bake oven and warming-chamberare entirely sepa rate and distinct, being made of separate sheets ofmetal-a provision which is further rendered necessary by the fact thatthe bakeoven is, as hereinbefore stated, detachable.

Fig. 5 shows a vertical transverse sectional rear view of thewarming-chamber and the manner in which the chamber is confined betweenthe framesA A. Fig. 3 shows in horizontal transverse section the mode inwhich the front and sides are held by the frame A. Fig. 2 shows the modeof attaching the top of the warming-chamber to the casting d, and therelations existing between the chamber and the top plate, 13. The bottomof the warming-chamber is in a plane above that of the ways 6 6, so thata space is left under the warming-ehamber for the reception of the rearparts of the oil-pots, said rear portions being shown extended withinthe space, and indicated by 71, in Figs. 1 and 2. Indepentt ently ol"the provision made by the space under the war1ning-chamberfor thereception of the extended or rear parts of the oil-pots, the spaceserves the useful purpose of admitting a free circulation of air to therear of the burners, as well. as to their fronts and sides. Above thesolid bottom plate, '13, of the wa-rming-ehamber is the ordinary grate,t", on which the utensils containing the articles to be warmed areplaced.

E is the bakeoven, which consists of a tin box having a lower open sideor bottom, and an open side in which the door is situated. The bottomedges of the oven are wired, as shown at It, Fig. 2, the wired portionsresting in grooves or depressions formed in the top plate, B, of thestove. As before stated, the portion 0 of the top plate, B, which iswithin the oven'space is open and removable. The bake-oven is providedwith a rearflue, Z, which communicates with the top fine, i, leading tothe escape-aperture Z. The escape-aperture is surrounded by theperforated and raised annular casting 2, so that on the placing of avessel or utensil thereon the draft and work of combustion may not beaffected.

It is evident that the construction here represented may be variouslymodified without departing from the substance of the in vent-ion.

The operation of the various parts of the stove hereinbefore describedwill be easily understood. may be separately withdrawn from the spacewhich they occupy under the top plate to a position beyond the frontlimit of the stove, and that they may, when so withdrawn, be usedentirely independently of the stove for various purposes of heating orcooking, the lamps being complete in themselves, and adapted for use asindependent heaters. The provision whereby a rearwardly-extended oilpotmaybe used is an important feature in this invention, and will bereadily appreciated. The dctachability of the warming-chamber is alsoimportant, as also is the construction and arrangement of parts wherebythe bake-oven is made conveniently removable from the stove.

I do not limit the several features of my invention to the exactmechanical construction hereinbefore described, as it is manifest thatthe same results may be accomplished by deviating more or less from thepreferred construction which I have set forth; but,

Having described my invention, I claim- 1. In an oil or gas stove, thecombination of aframe and lamps supported in sliding ways resting in theframe, substantially as set forth.
